Abstract

An interconnection structure used for sequentially bonding at least two cell slices and forming an excellent electrical connection. At least one of a front electrode and a back electrode of the cell slice is in a hollow structure, and the back electrode of the previous back electrode is connected with the front electrode of the next cell slice adjacent thereto through a conductive adhesive, thereby saving a large amount of front and back electrode paste, and reducing the cost of the shingled cell.
